William Williams, 21 years old, and Richard Cromwell, 20, are accused of robbing McGriff before shooting him once in the torso last month, a law enforcement official with knowledge of the case said.

The shooting occurred a few doors down from where McGriff, 32, lived on Staten Island. Williams was the alleged shooter, but both men have been charged with murder, robbery and criminal possession of a weapon and were awaiting arraignment late Wednesday, the official said.

It was not immediately clear if the suspects knew McGriff or it was a crime of opportunity, the official said. A fried of the victim’s had told investigators he had been on a cellphone call with McGriff when he heard the voices of two men and the line went dead. McGriff was found dead by police at about 2:00 a.m. on March 27 on Osgood Avenue in Staten Island’s Clifton section.

In addition to working as a disc jockey at clubs, McGriff made frequent appearances on Black Entertainment Television’s flagship program “106 & Park.” Previously, he had worked as an on-air radio disc jockey in Boston, Philadelphia and New York’s Hot97.

McGriff, a father of three children ranging in age from 11 years old to 10 months old, was memorialized and buried at a funeral service Tuesday.

The law enforcement official said Williams has four prior arrests, including one for a gunpoint rape. Cromwell has one prior arrest for allegedly stealing and crashing a car during a joyride. The disposition of those cases was not immediately available.
